Station terminal centralized control method and device based on intelligent telecontrol

Abstract

The invention discloses a station terminal centralized control method and device based on intelligent telecontrol. The method comprises the steps of acquiring the transmission data of a measuring and controlling device, a protecting device, a fault recording device, an on-line monitoring device, a watt hour meter and a PMU of a station terminal according to a predetermined standard; converting the acquired transmission data into preset data models, storing the data models in entries of a transmission data table, and updating the entries according to acquiring time when the transmission data are acquired repeatedly; setting the transmission priorities of all the entries in the transmission data table according to different service classifications and instantaneity requirement classifications; sending the entries with high transmission priorities to a main dispatch station according to the sequence of the transmission priorities. According to the station terminal centralized control method and device based on the intelligent telecontrol, the barrier that interaction is unavailable between different data types is broken through, repeated acquisition of data is avoided, the most important data information can be acquired by the main dispatch station as soon as possible, and the intelligentization level of data mining of the station terminal is improved.

Description

technical field [0001] The invention relates to a substation data transmission technology, in particular to a centralized control method and device at the station end based on intelligent telecontrol. Background technique [0002] At present, the data collection and remote transmission functions of the station control layer of substations and power plants are mainly realized by the following devices: telecontrol devices, protection information management devices, watt-hour meter collectors, PMU concentrators, etc. The remote transmission of different types or professional data in substations and power plants adopts different communication management devices for collection and transmission. [0003] The existing data remote inheritance methods of substations and power plants mainly have the following deficiencies: 1) Repeated transmission of data increases the burden on the network, resulting in the failure to submit important data in time; 2) There is no unified standard for...
